Twenty weeks into her pregnancy with baby Finn, Spelling was diagnosed with placenta previa, in which the placenta covers the cervix and causes severe bleeding. Her risks included the possibility of catastrophic hemorrhage that could even force termination of her pregnancy. (The condition resulted in part from conceiving Finn just one month after daughter Hattie's birth last October and having had three prior C-sections.)
